User blog:Dojobman25/7th gym rage

I’m on the seventh gym (dark type) and i keep getting beaten even though my lucario destroys the dark types. I’m mad because i almost had enough to buy alakazite but i lost like 30,000 pokedollars on the gym. It might just be bad luck, but im also really bad at competitive battling, so... i need some help.

Lucario is level 56, with calm mind, heal pulse, close combat, and aura sphere. Holding a fist plate. Not sure about nature, ability is steadfast, 31 IVs in atk, sp atk, and defense. I know it’s bad, could someone help me make it better?

Thanks in advance to anyone who does
